I'm working on a research project where we use Kinect (+ accelerometers) to detect one person's activities.

We're using the skeleton provided by the SDK and it doesn't work very well when the person is not facing the camera (which is understandable since it was originally designed for games). Also, the SDK skeleton doesn't seem to have any idea about morphological constraints (e.g. impossible arm rotations). Do you plan/is it possible to improve the skeleton tracking part ?

Buying in the dips might give you a median positive return (95% of the time you'll come out ahead) - but your expected return can easily still be negative due to what happens the other 5% of the time.

If you're following a very simple strategy based on past returns that seems to make money all the time, you should wonder what the rest of the market is afraid of that you can't see.

Imagine how well a "buy in the dips" strategy would pan out if you executed it during the Great Depression:
http://stockcharts.com/freecharts/historical/djia19201940.ht...

If you bought in at 200 after the market had plummeted from 380 down to 200, you'd probably be thinking your strategy is working pretty well - especially once it rallied back to 290 or so. But after that point you'd be waitinga LONG TIME to get your money back. It wasn't until 20 years later - the 1950's!! - that the DJIA finally sustained a level above 240 (and not before falling to 40 - good luck staying solvent through that!!).

And this is only because the US economy did eventually recover (thanks to World War II). Argentina's stock market never did recover. There's no such thing as "time diversification". In the long run, the variance of your annualized return increases: http://www.norstad.org/finance/risk-and-time.html

This is why the DJIA fell to 6500 in Oct 2009. If you bought then, you are probably feeling pretty smug now - but it's simply that the rest of the market was afraid of Great Depression II and you may not have even realised that it was a possibility.

To say that you can obtain a positive expected return by following any strategy that is solely based on what the price has done recently is just as "naive" as a retail investor who thinks they can beat HFT algorithms.

As the SEC says: "Past returns are never an indicator of future performance"

Rust can't run without it's runtime yet, which means the runtime needs to be wrapped into JavaScript code on the Emscripten side. The runtime needs some important parallel and memory functionality and last I heard most of it isn't easily to implement in JavaScript (workers and typed arrays and other HTML5 goodies probably bring it closer to being feasible).

NaCL is a more realistic target - in theory it should be as simple as making the compiler use NaCL's GCC instead of the system's C compiler. However, I don't know about how strict the sandboxing is, there might be certain things that the generated Rust code isn't allowed to do.
"Nobody can bring any medicine containing Methamphetamine or Amphetamine (Adderall and so on) into Japan."

It's the same in the USA without special permits. Methamphetamine and adderall are both classified under the same Schedule 2 criminal rubric. The investigation and prosecution of doctors who prescribe adderall, knowingly or not, to patients who then resell it to people without insurance or access to health care employs thousands -- probably tens of thousands -- of DEA and local police.

Different, not necessarily superior. The *racetams impact acetylcholine levels, and this neurochem plays a part in memory formation and retention. Additionally racetams are associated with increased oxygen flow in the brain. Anecdotal evidence suggests they can cause headaches if you aren't taking choline, but also is strongly positive towards sharper memory. They're easily obtainable as supplements, and unlike classic amphetamine-based stimulants, aren't demonstrably neurotoxic or addictive. In my opinion, however, there is no comparing/substituting them to traditional stimulants that allow for hours of immediate focus. Take both. Or better yet titrate the addictive amphetamine down with adrafinil or modafinil. Adrafinil is an effective way to avoid a lack of sleep's associated cognitive deficits. It seems to be correlated in people with subjectively low IQs though http://www.ncbi.nlm.nih.gov/pubmed/16140369

1: I've been long TSLA since the IPO - I simply bought more stock with cash on hand. I'm not just median riding - although that is a relatively effective strategy for high earning companies/growth.

2: Risk is risk - TANSTAAFL. Great Depression risk is there just as there is nuclear war risk. I take it because I can. I try and make sure I pay the right rates though.

3: DJIA is not the entire market - it's a highly constrained subset.

4: Following past strategies does have positive value - it's what investing (and everything thing you know) is all about.

I'm not a JS programmer, but isn't that just an array? Which extends Object. Which has all the failings that the article mentions? What happens when you try to insert hasOwnProperty? Do you lose access to the superclass hasOwnProperty like the {} object literal's drawback the article mentions? I suspect you do.
That has a couple of problems. Try this:

> var hash = [];
undefined
> hash
[]
> hash['length']
0
> // Hey! That should have been undefined, not 0!
> hash['length'] = 'test'
RangeError: Invalid array length
> // And I can't set it either!

Also, the part where you're doing hash[hash] doesn't do at all what you think. When you write this code:

hash[hash] = whatever;

What you're really doing is:

hash[ hash.toString() ] = whatever;

And with hash being an array, hash.toString() is highly browser dependent. In Chrome, if you don't have any numeric array keys, then hash.toString() is "" regardless of your non-numeric keys (at least in the version I'm testing). So you may well be really doing this in Chrome:

hash[""] = whatever; // Oops

If you do want to use a native JavaScript type as a hash, the one to use is Object, not Array. Simply change the first line of your test to:

var hash = {};

and go from there.

This still doesn't solve the name collisions, but is plenty useful anyway.

If you do want a more fool-proof hash that lets you use any string as a key without fear, I'm pretty sure you need to write some code like the Hash class I posted. You still couldn't do the hash[hash] - or hash.get(hash) - because of the dependence on .toString(), but any string key would work. You could even get fancy and give the Hash class some kind of useful .toString() method so you could use hash[hash] - having your own code here opens up those kinds of possibilities.

Work-Life Balance Is For Losers, Not Closers
Does Javascript run outside the browser and outside of a platform like Node.js? I want stuff that can run on bare metal as well as on top of other code (software platform).

Personally, I don't care about browsers. One application of a gazillion possible applications. They are an afterthought. I care about sockets and the ability to connect a machine to other machines over a network.

I care about code that can boot a computer, code that can be used to write drivers to control hardware (maybe some new hardware that just hits the market), and code that let's us build on top of that. With this code we should be able to build a kernel and userspace utilities and thereby manage to operate the hardware. Once everything is up and running, then we can install any scripting language we want. We don't have to use the same language we used to build the system to do any work after that, but we could. Indeed many higher level things are written in C, e.g., the interpreters for languages like JavaScript and the web browsers they are a part of. Maybe there's a reason for that?

If the best code for building from the ground up on any given piece of hardware is Javascript, it's news to me. Any examples? I have a new piece of hardware. Can I boot it using JavaScript? Can I control the hardware with JavaScript?

I believe the OP just wanted to do parsing in userspace. Personally I use C for that (generated from flex), but there are countless languages that can do parsing. Why he chose to attack C I have no idea. Like I said, once the computer is up and running (thanks to C), we can use any language we like. We can run "web browsers", and software platforms. And JavaScript. So, have fun with your JavaScript. But I'm pretty sure C isn't going away anytime soon.

> Without V8, there is no JavaScript on the server-side

The first implementation of server side Javascript was nearly 20 years ago:

http://en.wikipedia.org/wiki/JavaScript#Server-side_JavaScri...

Naturally, it was never all that popular, but... it has been around.
No question about the practical value of any of this, as the power of these abilities has been discussed and dissected many times, but I'd like to make a brief case as to _why_ some find this distasteful, after many years of reading forums like this and talking to people who openly expressed hatred of it (it being non-verbal signals, subtext, etc.)

First, there is the issue of merit. It seems like this grants those with good social intelligence an "unfair" advantage, since the skills involved aren't involved in actually creating/fixing/understanding anything concrete; its power comes from its ability to persaude, detect, and signal. Some perceive this sort of skill as seeming fake and superficial.

Second, it flies in the face of the idea of radical honesty and transparency, as it deals with situations and ideas having to do with saying one thing (or nothing at all) but meaning another. This feels very dishonest, and ugly. Some would like to live in a world where absolutely everything is completely explicitly stated, and no one gets offended, but uses everything said as a learning experience. This may seem naive (because the ability to think and say things others may find subjectively offensive is great), but the desire persists nonetheless.

I'm personally torn on the subject, as both ways have their serious negatives, but it's worth stating here anyway.

This seems pretty good from a first glance; provides a "Standard" or "Classic" option to select between Apple's and Google's Maps. If you just care about tiles (rather than e.g. transit directions) then this should be a good stop-gap until Google releases their own version. It's a nicer experience than the mobile Google Maps site.

That's great that your TSLA investment is doing so well! My mum bought me some BHP shares in the early 80s that are doing great too. Thanks Mum!

But I still think it's not really being honest to say that the key to investing is as simple as not selling in a crisis.
The importance of learning some sort of social intelligence is so underrated. You see all these front page posts on hacker news "I taught my 5 year old son and daughter how to program in five different languages" like its something that will really better these children's lives. You want a happy successful kid? Teach them the art of being social and having meaningful interactions with other people. I've wasted so much of my life trying to be the best student or programmer I could possibly be. I turned 24 this year and I'm proud of how well I've done and what I've accomplished in my career to date, but without friends to enjoy it with, success is pretty shallow.

The startup scene in France is glacial. During the presidential elections, the only political figure who seem to get it and bound to fix this mess was François Bayrou, while the remainder were focusing on saving what remains of our heavy industries.

I randomly watch news/docs about some French "startup", and the spread mean size seems to be 20 to 100 employees. That's enough to make you think what "bootstrapping" means here.

Even without talking about that side of things, it's extremely hard to find anyone technically truly competent to sidekick with, let alone in technologies compatible with startup rhythms (even Rails and Django are a rarity, the huge flock only knows C# and Java at a very, ahem, academic level). Not exactly helpful if you want to build your MVP quickly.

I'm not even talking about the legal paperworks that would sink a founder's time like your nearby blackhole. I'm contemplating doing this myself since a few years and the amount of crap you have to wade through is astounding. The sanest solution is moving to the UK (but my personal situation prevents that, for now).

It's a pretty good illustration of why associative arrays in Javascript are a design failure, by conflating different notions in the same implementations:

- objects are not hashes

- hashes are not arrays

It sounds like somebody reading the classic quote by Saint Exupéry, "A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.", and concluding: "Well, if I mash all the elements to a paste, there won't be anything to take away."

Schools are boring, horrible and pointless experience. But if you're drugged enough you may just ignore that and happily buzz along like a zombie. Which in turn will lead you to not becoming angry with this crap, and not using yourself to change schools in the future.

Some of the more hazardous side effects of adderall:
• Dangerous increase in blood pressure
• Tachycardia or a high pulse rate
• Irregular heart rate
• Difficulty breathing
• Chest pain
• Allergic reaction that includes swelling and redness in the eyes or throat
• Migraine headaches
• Syncope or losing consciousness
• Blurry or double vision
• Seizure activity and excessive and uncontrollable shaking
• Extreme nervousness and paranoid delusions
• Mood swings that include hostility and severe aggression
• Depression
I hear you. I do feel that, like many other skills, this also can be learned and mastered. There have been times when I've been pretty adept at recognizing and responding to signals. But over the past few years, I have lapsed.

Just as an example: today, at a talk, I was talking to this woman and we had a pleasant conversation. Then, as the talk is about to start, she says something to the effect of "I'd love to learn more about your work". My response (with a mouthful of pizza)? "Sure!". And then I focused back on the speaker as he was about to start speaking. Much later I realized she wanted to continue the conversation later, and wanted my card or some contact info. But by then she was gone (she left early).

So, for me, it's not that I don't pick up signals; I do pick up many, but they have a much lower priority in the brain's CPU and my responses don't incorporate the signals. My brain finally realizes the inputs way after the opportunity has passed.
